The functionality of workflow services can be illustrated using a simple order approval business process to approve or reject an order, as shown in Figure 15-2. requested items. Approval and rejection is a two-step process involving an initial approver and the manager of the
school causes essay, initial approver. The order is first assigned to the Supervisor role. Once a user belonging to
king lear relationships, the Supervisor role approves the order, it is
essay academic, sent to
king lear relationships, this user's manager for final approval. Figure 15-2 BPEL Workflow.
Oracle BPEL Process Manager Order Booking Tutorial for instructions on designing an order approval business process to approve or reject an order. 15.2.2 Workflow Services Components. Figure 15-3 shows the following workflow services components: The task service provides task state management and persistence of tasks. In addition to these services, the task service exposes operations to update a task, complete a task, escalate and reassign tasks, and so on. The task service is used by the Oracle BPEL Worklist Application to retrieve tasks assigned to
mary leapor summary, users. This service also determines if notifications are to
parent-child relationships essay, be sent to users and groups when the state of the
thesis statement on binge, task changes. The task service consists of the following services. Task Routing Service. The task routing service offers services to route, escalate, and reassign the
king lear parent-child relationships, task. The service makes these decisions by interpreting a declarative specification in the form of the
leapor an essay summary, routing slip.
Task Query Service. The task query service queries tasks for a user based on a variety of search criterion such as keyword, category, status, business process, attribute values, history information of a task, and so on.
King Parent-child! Task Metadata Service. The task metadata service exposes operations to retrieve metadata information related to a task. The identity service is
school dropouts causes and effects, a thin Web service layer on
king essay top of the Oracle Application Server 10 g security infrastructure or any custom user repository.
It enables authentication and authorization of
thesis statement drinking users and the lookup of user properties, roles, group memberships, and privileges.
Lear Essay! The notification service delivers notifications with the specified content to the specified user to any of the following channels: e-mail, telephone voice message, pager, fax, and SMS. See Notifications from Workflow Services for more information. User Metadata Service. The user metadata service manages metadata related to workflow users, such as user work queues, preferences, vacation, and delegation rules. Runtime config service. The runtime config service provides methods for
statement, managing metadata used in the task service run time environment. It principally supports management of task payload flex field mappings. Figure 15-3 Workflow Services Components. Figure 15-4 shows the interactions between the services and the business process. Figure 15-4 Workflow Services and Business Process Interactions.
15.3 Use Cases for Workflow Services. Using workflow services is demonstrated in
king parent-child essay the VacationRequest, AutoLoanDemo, ExpenseRequestApproval, LoanDemoPlus, DocumentReview, HelpDeskServiceRequest, and OrderApproval demos. The following sections describe multiple use cases for workflow services. 15.3.1 Assigning a Task to a User or Role.
Thesis Drinking! A vacation request process may start with getting the vacation details from a user and then routing the request to their manager for
essay, approval. User details and the organizational hierarchy can be looked up from a user directory or store. This scenario, shown in Figure 15-5, is described in the OrderApproval sample. Figure 15-5 Assigning Tasks to a User or Role from a Directory. 15.3.2 Using the Various Participant Types. A task can be routed through multiple users with a group vote, management chain, or sequential list of approvers participant type. For example, consider a loan request that is part of the loan approval flow.
The loan request may first be assigned to a loan agent role. After a specific loan agent acquires and accepts the loan, the
degree of science, loan may be routed further through multiple levels of management if the
relationships, loan amount is greater that $100,000. This scenario, shown in Figure 15-6, is described in
essay academic writing the LoanDemoPlus sample. Figure 15-6 Flow Patterns and Routing Policies. See Participant Types in Workflow Services for the various flow types supported by workflow services.
You can use these types as building blocks to create complex workflows. 15.3.3 Escalation, Expiration, and Delegation. A high-priority task can be assigned to a certain user or role based on the task type. However, if the user does not act on it in a certain time, the task may expire and in turn be escalated to the manager for further action. As part of the escalation, you may also notify the users by e-mail, telephone voice message, SMS, pager, or fax. Similarly, a manager may delegate tasks from one reportee to another to
king parent-child relationships, balance the load between various task assignees.
All tasks defined in BPEL have an associated expiration date. Additionally, you may specify escalation or renewal policies, as shown in Figure 15-7. For example, consider a support call, which is part of the HelpDeskServiceRequest process. A high-priority task may be assigned to a certain user and if the user does not respond in two days, then the task is routed to
statement on binge drinking, the manager for further action. Figure 15-7 Escalation and Notification. 15.3.4 Automatic Assignment and
king lear parent-child relationships, Delegation. A user may decide to have another user perform tasks on their behalf.
High And Effects Essay! Tasks can be explicitly delegated from the
parent-child relationships, Oracle BPEL Worklist Application or can be automatically delegated. For example, a manager sets up a vacation rule saying that all their high priority tasks are automatically routed to one of their reports while the manager is on vacation. In some cases, tasks can be routed to
high dropouts causes essay, different individuals based on the content of the task.
Another example of
king parent-child essay automatic routing is to allocate tasks among multiple individuals belonging to a group.
Leapor An Essay! For example, a help desk supervisor decides to allocate all tasks for the western region based on a round robin basis or assign tasks to the individual with the lowest number of outstanding tasks (the least busy). 15.3.5 Work Queues and Proxy Support. It is
king, often required that one user be provided with access to part of another user's worklist. For example, an executive decides to provide access to expense approvals within a certain limit to their secretary. Work queues allow you to create a custom view to group a subset of tasks in the worklist (say high priority tasks, tasks due in 24 hours, expense approval tasks, and
high school causes essay, so on).
King Lear Parent-child Essay! These work queues can then be granted to other users who can then act on the task owner's behalf. For example, in
dropouts causes essay the scenario described above, the executive can create a delegated expense approvals work queue for expenses below $5000. 15.3.6 The Oracle BPEL Worklist Application.
Users typically access tasks assigned to them by using the Oracle BPEL Worklist Application, as shown in Figure 15-8. A worklist consists of tasks assigned to the user as well as the groups to which they belong. A task may also include forms and attachments in
king relationships addition to other task details such as history, comments, and approval sequence. The worklist may also be accessed from OracleAS Portal or other clients to act on tasks as well as get productivity reports. The Oracle BPEL Worklist Application can be customized and extended based on
high causes and effects essay the specific needs of an
relationships essay application. See Chapter 16, Worklist Application for details about
statement drinking, worklist functionality and the sample Oracle BPEL Worklist Application. Figure 15-8 Oracle BPEL Worklist Application#x2014;Access Tasks, Forms, Attachments, and Reports.
King Lear Parent-child Relationships! 15.4 Participant Types in
mary summary Workflow Services. Oracle BPEL Process Manager provides a library of participant types (known in previous releases as workflow patterns).
You can choose a participant type that meets your business requirement and
lear parent-child essay, model your workflow based on the participant type. Oracle BPEL Process Manager supports the following participant types: Single Approver #x2014; used for
high school causes essay, a single user to
lear, act on a task. If the task is assigned to a role or group with multiple users, one of the
chroniqueur de on essayer, members must claim the task and act on
lear essay it. Based on the user's action, you define what the business process does. Group Vote #x2014; used when multiple users, working in parallel, must take action simultaneously, such as in a hiring situation when multiple users vote to
thesis on binge, hire or reject an applicant. You specify the voting percentage that is needed for
essay, the outcome to take effect, such as a majority vote or a unanimous vote.
Leapor An Essay On Women Summary! Management Chain#x2014;used to route tasks for
lear, approval to multiple users in a management chain hierarchy.
Statement Drinking! You specify the task participants as a management chain list or a list of users. Sequential list of approvers (extension of a sequential workflow)#x2014;used to
lear, create a list of
on binge sequential participants for
lear parent-child relationships essay, a workflow. This type is similar to
birth control, the management chain participant type, except that with that type, the users are part of an organization hierarchy.
For the
relationships, sequential list of approvers participant type, they can be any list of users or groups. FYI assignee #x2014; used when a task is sent to a user, but the business process does not wait for
an essay, a user response; it just continues. FYI assignees cannot directly impact the outcome of
lear a task, but in some cases can provide comments or add attachments. External Routing Service #x2014;used to configure an external routing service that dynamically determines the participants in the workflow. If this participant type is specified, all other participant types are ignored.
It is assumed that the external routing service provides a list of participant types (single approver, list of approvers, group vote, and
thesis statement on binge drinking, so on) at run time to determine the routing of the task. 15.4.1 Continuing Workflows from
king lear, Other Workflows.
Academic Topics! You can have situations where you need to continue a previous workflow task in the current workflow task. Oracle BPEL Process Manager enables you to include the task history, comments, and
relationships, attachments from the previous task. This provides you with a complete end-to-end audit trail. 15.5 Overview of the Modeling Process. The modeling process consists of creating a human task, associating it with a BPEL process, and generating the format for displaying the human task during run time in the Oracle BPEL Worklist Application. This section provides a brief overview of these modeling tasks and provides references to specific modeling instructions. 15.5.1 Create a Human Task Definition with the Human Task Editor. The Human Task editor enables you to

This information is
thesis on binge, saved to a metadata task configuration file with a .task extension. 15.5.2 Associate the Human Task Definition with a BPEL Process. You associate the .task file that consists of the human task settings with a BPEL process. Association is made with a human task activity that you drag and drop into your BPEL process for configuring.
Lear Parent-child Relationships! You also define the task definition, task initiator, task priority, and
school dropouts essay, map the task parameter that carries the input data to a BPEL variable. You can also define advanced features, such as the
relationships, scope and
thesis statement drinking, global task variables names (instead of accepting the default names), task owner, identification key, BPEL callback customizations, and
king relationships essay, whether to extend the human task to include other workflow tasks. When association is
school essay, complete, a Task Service partner link is created. The Task Service exposes the operations required to
parent-child relationships essay, act on the task. 15.5.3 Generate the Task Display Form.
You generate the layout of the task display form used for displaying the task header, body (task payload), and footer details at run time in Oracle BPEL Worklist Application. The task display form defines the display mechanism for the task payload (data in the task) in the Oracle BPEL Worklist Application. Two types of task display forms are available for use: simple task form and custom task form. 15.6 Task 1: Creating the Human Task Definition with the Human Task Editor. The Human Task editor enables you to
thesis statement on binge, define the metadata for the task.
This editor enables you to specify human task settings, such as task outcome, payload structure, task participants, assignment and routing policy, expiration and
king lear, escalation policy, notification settings, and so on.

de on essayer Figure 15-12 after you have configured a participant type. These sections are only available for selection after a participant type has been created. Users and groups for each of the participant types can be specified either statically or dynamically.When the users and groups are specified statically (or by browsing the identity service), the
lear relationships, values can be either of the following:
A single user or group (for example, jstein ), which in
essay academic topics the case of a single approver, is captured as follows: A delimited string of users or groups (for example, jstein , wfaulk , cdickens ), which in the case of a single approver, is captured as follows: You may have a business requirement to
lear parent-child relationships essay, create a dynamic list of task approvers specified in a payload variable. This XPath expression can resolve to zero or more XML nodes. Each node value can be either of the
academic, following: A single user or group. A delimited string of users or groups. For example, the following task shows that the payload message attribute is of type xsd:String and its value is a comma-delimited string of approvers. This node can be used to specify the participants. The default delimiter for the assignee delimited string is a comma ( , ). This delimiter can be changed using the assigneeDelimiter XML element in
relationships essay the wf-config.xml file.
This delimiter applies to all workflows in the system. Specifying participants in this manner is applicable to all participant types, although they are interpreted differently for each type. For example: In a single user participant type, the task is assigned to everyone evaluated. In a sequential list of approvers participant type, the task is
thesis statement drinking, sequentially assigned to users and groups evaluated in the list. In a group vote participant type, a task is created for
king lear, each user and group evaluated in the list.

For example, participant LoanAgentGroup and participant Supervisor have 3 days to act on the task between them, as shown in Figure 15-21: Figure 15-21 Expire After Policy.

The global expiration duration is always decremented by the time elapsed in the task. The policy to interpret the participant level expiration for the participants is described below: Management Chain #x2014; Each participant in the management chain gets the same expiration duration. The duration is not for all the assignments resulting from this assignment. If the task expires at any of the assignments in the management chain, the task expires and the escalation and renewal policy is

In the following routing slip sample, participant Loan Agent Group has an expiration duration of
king lear parent-child 1 day and participant Loan Agent Supervisor does not have any expiration duration on
birth control the task, even though an expiration duration is specified at the routing slip level. In this example, the

Parent-child Relationships Essay! This enables you to update the metadata. 15.7.5 Viewing the Generated Human Task Activity. When you have completed modeling the human task activity, the human task is generated in the designer window. Figure 15-29 shows how a workflow interaction is modeled in
thesis statement on binge Oracle BPEL Process Manager. Figure 15-29 also illustrates the
king lear parent-child relationships, interaction when no BPEL callbacks are modeled.
De On! In this case, once a task is complete, the BPEL process is called back with the
relationships, completed task. No intermediary events are propagated to the BPEL process instance.
It is recommended that any user customizations be done in the first assign, AssignTaskAttributes, and
academic writing topics, that AssignSystemTaskAttributes not be changed.
Lear Essay! Figure 15-29 Workflow Interaction Modeling. Figure 15-30 shows a workflow interaction in Oracle JDeveloper. Figure 15-30 Workflow Interaction Modeling in Oracle JDeveloper. If intermediary events need to be propagated to the BPEL process instance, select the Allow task and routing customization in BPEL callbacks check box in both the Advanced tab of the Human Task window and the Advanced Settings section of the Human Task editor. When these options are selected, the workflow service invokes callbacks in the BPEL instance during each update of the task.
The callbacks are listed in the TaskService.wsdl file and described below: onTaskCompleted #x2014; This callback is invoked when the task is completed, expired, withdrawn, or errored. onTaskAssigned #x2014; This callback is invoked when the task is assigned to a new set of assignees due to the following actions: Skip current assignment. Override routing slip. onTaskUpdated #x2014; This callback is
on women, invoked for any other update to the task that does not fall in the onTaskComplete or onTaskAssigned callback. This includes updates on tasks due to request for information, submit information, escalation, reassign, and so on. onSubTaskUpdated #x2014; This callback is invoked for any update to a subtask. Figure 15-31 shows how a workflow interaction with callbacks is modeled in Oracle BPEL Process Manager.
Once this task is initiated, a while loop is used to
king lear parent-child essay, receive messages until the
academic topics, task is complete. The while loop contains a pick with four onMessage branches #x2014; one for each of the
king lear essay, above-mentioned callback operations.
Writing Topics! The workflow interaction works fine even if nothing is changed in the onMessage branches, meaning that customizations in the onMessage branches are not required. In this scenario, a workflow context is captured in the BPEL instance. This context can be used for
king parent-child relationships essay, all interaction with the workflow services. For example, if you want to
birth control, reassign a task if it is assigned to a group, then you need the workflow context for
lear parent-child essay, the reassignTask operation on
drinking the Task Service.
King Relationships Essay! It is recommended that any user customizations be done in the first assign, AssignTaskAttributes, and that AssignSystemTaskAttributes not be changed.
Figure 15-31 Workflow Interaction Modeling (with Callbacks) Figure 15-32 shows a workflow interaction in Oracle JDeveloper. Figure 15-32 Workflow Interaction Modeling (with Callbacks) in Oracle JDeveloper. 15.7.5.2 Including the Task History from Other Workflows. When the task history is included in
birth control a workflow, the generated BPEL process described in the previous two sections is similar, with the following differences: The BPEL variable from the workflow whose task history is to be included is reused and no new BPEL variable is created. The first invoke activity invokes the
king lear parent-child, reinitiate operation instead of the
birth control, initiate operation. In many cases, the outcome of a task determines the flow of the business process. To facilitate modeling of the business logic, when a user task is generated, a BPEL switch activity is
king parent-child relationships, also generated with prebuilt BPEL case activities. By default, one case branch is created for each outcome selected during creation of the task. An otherwise branch is also generated in the switch to represent cases when the task is withdrawn, expired, or errored.
The task carries a payload in it. If the payload is set from a business process variable, then an assign activity with the name copyPayloadFromTask is created in
high school each of the
lear relationships, case and
essay academic, otherwise branches to copy the payload from the task back to its source. If the payload is expressed as other XPath expressions (such as ora:getNodes(. ) ), then this assign is not created because of the lack of a process variable to copy the payload back. If the payload does not need to be modified, then this assign can be removed. 15.7.6.2 Case Statements for Other Task Conclusions. By default, the switch activity contains case statements for the outcomes only. The other task conclusions are captured in the otherwise branch. These conclusions are as follows:
The task is withdrawn. The task is errored. The task is expired. If business logic must be added for each of these other conclusions, then case statements can be added for each of the preceding conditions. The case statements can be created as shown in the following BPEL segment. The XPath conditions for the other conclusions in the case activities for each of the preceding cases are shown in
king relationships essay bold.
Birth Control! 15.8 Task 3: Generating the Task Display Form.
King Essay! The task display form defines the display mechanism for the task payload in the Oracle BPEL Worklist Application. This section describes the different types of task display forms you can use. This section contains the following topics:
15.8.1 Overview of Task Display Forms. The task display form for the human task can be automatically generated and then customized or developed completely from the beginning using the workflow APIs. In the automatically generated case, a set of seeded templates and regions are used for the task forms. There are two methods for generating forms associated with the task definition: Automatically generate a simple task form #x2014; JSP-based forms that use the standard header, body, and footer template.
Custom task form #x2014; enables you to select one of the existing templates and regions to create a task form. You can also specify which task parameters to display in the form. When task display forms are generated, a .tform file is created, which includes a template URI and region information. The .tform file is included in the process deployment archive and is deployed during process deployment.
Birth Control! 15.8.2 Selecting a Task Display Form. Follow these instructions to generate a task display form for the human task. Go to
parent-child relationships, the Application Navigator in Oracle JDeveloper. Right-click the folder of the human task for which to create a task display form (for this example, ExpenseApproval of the ExpenseRequest BPEL process in selected). The following menu of selections appears.
See the following sections for details about generating the different types of task forms: 15.8.2.1 Preview Release of Task Display Form Support for

king parent-child relationships essay the Header1.jsp file. Body region #x2014; this region is generated based on the task parameters.
Depending on the XSD used in the task, it is
an essay on women, either generated as a list of values or as a table (for repeating items). If you specified the parameter to be modifiable through the worklist on the Add Task Parameter window in Step 2, it displays as an
king lear relationships editable field in the form. Otherwise, the field displays as read-only. The information for this region is contained in the payload-body.jsp file and
statement drinking, the payload-body.xml mapping file. After generation, if you want to change any read-only parameters, you can modify the
relationships, payload-body.xml file. Footer region #x2014; this region has an area for comments, attachments, and a short history of the task routing. This information is contained in the Footer1.jsp file.
A .tform file is
on women, generated. The contents of this file are as follows: 15.8.3.1 Payload File for the Autogenerated JSP. Two files are automatically generated to display the payload for the autogenerated JSP: A default JSP file named payload-body.jsp . This file is added to
king parent-child essay, the HTML root directory of your project, which is by default the
thesis statement drinking, public_html directory.
A mapping XML file named payload-body.xml . This file is added to the same directory of your project as payload-body.jsp. If you select Custom Task Form in Step 2, you can specify a unique file name for the autogenerated JSP. The mapping XML file is created based on the JSP file name. You can also select the payload elements to
lear relationships, include in the autogenerated JSP. For example, if the JSP file is named autogenerate-body.jsp , then the mapping XML file is named autogenerate-body.xml . The JSP run-time library and the BPMWorkflow library are automatically added to your BPEL project for compilation of the JSP file. The default JSP is designed with two goals in
birth control mind: To present you with a simple form; that is, an XSD tree with a depth of more than three must be shown in a more readable way in the JSP.
The default JSP must require minimum modification. If modification is unavoidable, it can be easily performed with a user interface tool. To attain these goals, instead of presenting a tree structure that mimics the payload XSD structure, the default JSP groups the entire payload structure in sections. It groups simple types that belong to
essay, the same parents and makes them sections. For example, assume you provide the
birth control, following payload XSD: This XSD has the structure shown in
lear essay Figure 15-33. Figure 15-33 Structure of the XSD for myCompanyType. In the default JSP, based on the structure of the leaf nodes, there are three sections: , , and . These three sections are named according to their parents' names; that is, the sections are named board , my Company , and department , respectively.
In the board section, there are two fields, size and head . Each of these fields are in an editable HTML input type.The section department is different from other sections and can have multiple occurrences ( maxOccurs 1 ). In this case, all the fields in this section (that is, size , head , and function ) are horizontally presented in a table, with each row representing one department .
Thesis Statement Drinking! This is
parent-child essay, called a table section. There is a plus ( + ) button for
writing, adding a row (department) and a minus ( - ) button for subtracting a row (department) for the department table section.Unlike a regular section, it is not necessarily true that all the fields belong to the same XSD parent in
king lear relationships a table section. For example, suppose the head element has two elements: employeeNumber and dateOfBirth . Since these two elements have maxOccurs set to less than or equal to 1 , they are shown in
mary an essay on women summary the same department table section. This is a desired behavior, because adding a row in the department table not only adds a size and a function field, but also adds the head information fields in the same department row. This makes it easy to move through complicated payload instances.
Lear Relationships Essay! Nested multiple ( maxOccurs 1 ) elements are supported. Assume the department element has a groupMember child element whose maxOccurs is unbounded. In that case, the
birth control, parent element department is presented in
king parent-child relationships a table section while the child groupMember elements are presented in different child table sections. The parent department table section has a column called group member that contains an HTML href link pointing to its corresponding child group member section in each department row.
Pressing the + button in the parent department section not only adds a row in the parent table, but also adds a child section for
on binge drinking, that corresponding new row. The default JSP in the current release has the following limitations: XSDs that contain recursive elements are not supported. The default JSP shows all the
king lear essay, simple types defined in the payload XSD. If multiple simple types belong to the same XSD choice block, all these simple types are shown in the default JSP.
Although simple types are preserved in
essay academic the JSP, XSD restrictions are not relevant. Only payloads copied from variables that are not simple types are supported. For example, if the query is bpws:getVariableData(var) or bpws:getVariableData(var, part) and the variable is a simple type, then JSP generation fails. Note that bpws:getVariableData(var, part, query) and bpws:getVariableData(var, query) work even if the queried data is a simple type. You only need to make sure the variable itself is not a simple type. XSI extensions are not supported. No special handling of XSD order indicators occurs (that is, choice , all , and sequence ). For example, the default JSP does not check if you entered both firstname and lastname : 15.8.3.1.1 Customizing the Autogenerated JSP. The autogenerated default JSP is
relationships essay, generic, and so may require changes to improve its look and feel. The JSP works in conjunction with the mapping file to determine which elements in the payload are displayed in the form.
De On! 15.8.3.1.2 Customizing the Mapping File.
The mapping file gives you control of the presentation.
King Relationships! The mapping file is an XML file that contains a list of viewable fields. The root element in the mapping file contains its targetNameSpace , other namespaces, and xmlEditable as its attributes.
Essay Academic Topics! All the elements that are simple types are listed as fields in the mapping file. Along with these elements, their immediate parents are listed as well for multilanguage support.
Each field has three properties defined in the mapping file. They are xpath , editable , and
king, resource_key . The xpath property defines the XPath of this field. It is always prefixed by /ns0:task/ns0:payload . This is the XPath to the root of the
thesis for the, payload object.
Essay! When maxOccurs is greater than 1 , it is denoted by
. For example, /ns0:task/ns0:payload/company[*]/ceo shows that maxOccurs is statement on binge, greater than 1 for lear, the company field. Do not modify this XPath field because it is also a unique key that determines the identity of the field.
The editable property defines if this field is editable. It defaults to true . If the value of this field is changed to false , the default JSP shows a disabled text field that disallows value changes.
Leapor On Women! The resource_key property is for
king parent-child essay, multilanguage support. To ensure that your autogenerated JSP shows a preferred language other than English, you must supply a resource bundle. Follow these steps to add a resource bundle: Create a bundle file (for example, MyBundle ). This file points to a properties file that resides at the root of the project.
Thesis Degree Of Master! The following code shows an example of MyBundle_en-US.properties : In this case, if a field is defined in your mapping file as follows. in the default JSP returns the string i18n Task if your locale is set to en-US . Similarly, if your locale is set to French, the proper properties file ( MyBundle_fr.properties ) is picked up. Specify the resource bundle name and
essay, location in the Resource Details window of the Human Task editor, as shown in
birth control Specifying Multilingual Settings. 15.8.3.1.3 Customizing the Default JSP.
If the
king lear essay, mapping file does not provide enough control, you can modify the default JSP file. Only modify the
essay academic, section after the label: Most JSP modifications can be made in the JSP design view of Oracle JDeveloper. By default, all the fields are set to text field. If you want to change a text field to a text area, you can do the following.
Parent-child Relationships Essay! Select Text Area in the Component Palette , as shown in Figure 15-34. Figure 15-34 Oracle JDeveloper JSP Design View. Drop it into
mary leapor summary the position of the text field you want to replace. Note that the name of the text field is set by calling the function oracle.bpel.services.workflow.worklist.payload.PayloadFormGenerator.constructName(String xpath) , and the value of the field is
lear parent-child essay, set by PayloadFormGenerator.selectNodeValue(Element payload, String xpath, Map namespace) . These functions must be used to
essay writing, construct form field names and to retrieve form field values. Set the
lear parent-child relationships, text area's name and value to the same name and value as the text field.
Delete the text field. In the place you want to insert text or other HTML elements that are not in a table, add text by typing it or add an HTML element by dragging and dropping the HTML component from the Component Pallet . If the place you want to insert HTML elements is in an HTML table, to insert text or a horizontal rule, first add a table row by clicking a row, right-clicking, and
on women, selecting Insert Row . After a row is inserted, you may need to
parent-child relationships, merge all the cells in the row by selecting all the cells in the row and right-clicking to select Merge Cells . Then you can either type your text or drag and drop your HTML component. If you want to change the layout of the table or form, highlight the section you want to modify, right-click, and select table or form. If you want to format the text, use the toolbar's color and style buttons. It is recommended that you modify the default JSP's look and feel only. You should preserve the functions being used in the JSP. You must not alter the
high school causes, hidden parameters being submitted in the HTML form, because the Update button invokes form submission to the WFTaskUpdate that expects certain values. If your change is complicated and has programming logic in it, you must switch to the source view and modify the JSP code directly.
By putting the statement %@ page pageEncoding=UTF-8 % in the default JSP, UTF-8 is set as the default encoding.

Follow these instructions if you want to customize the JSP page to display a selectable check box instead of a text box. Note that the input for the status is
king lear parent-child relationships essay, generated as follows. Substitute the entire code block shown in Step 1 with the following code block: Add the following JavaScript . This is required because the value for the check box field in JavaScript is always the value defined in
degree of master of science the input element. 15.8.4 Generating a Custom Task Display Form. For this release, task display forms are generated by using templates consisting of different regions.
Oracle JDeveloper automatically includes three templates and two default JSPs: The three templates are as follows: Three Region JSP #x2014; Consists of the header, body and footer regions. These regions can be displayed by using custom JSP, XSL, default JSP, or autogenerated JSP files. The automatically generated JSP displays the body region. Two Region JSP #x2014; Consists of the header and footer regions. One Region JSP #x2014; Consists of the body region. The two default JSPs are as follows:
The header JSP displays task attributes such as task number, priority, title, and so on. The footer JSP displays task attributes such as attachment, comments, and so on. The custom task display form enables you to select the template and rendering type for
king parent-child relationships essay, displaying task details. Select Custom Task Form from the list shown in Step 2. The Task Form Display window appears. Select a template from the Current Template list. Three are three seeded regions (three region JSP, two region JSP, and one region JSP). After selecting a region, you can specify how to render it. See the
essay academic, following sections for details about generating the different types of custom task display forms: This option enables you to automatically generate a form for the payload of the
king relationships essay, task.
You can also optionally specify which particular task parameters you want to
writing topics, include in the displayed form. Select Auto JSP from the Body list in the Rendering section. An icon displays to the right of Body.jsp in the Source section. The Payload Mapping window appears. This window enables you to select message attributes. Select message attributes to include in the autogenerated JSP. Click OK to
lear parent-child essay, return to
high school dropouts causes and effects essay, the Task Form Display window. This option enables you to invoke an external custom JSP to display the task details. You can also specify URL parameters to pass to this JSP at run time. Three parameters are passed in by default #x2014; taskID , version , and workflowContext . Additional parameters must be explicitly specified.
Select Custom JSP from the
king lear relationships, Header list in the Rendering section. A second icon displays to the right of the Source section for editing custom JSP parameters. Enter the custom JSP file name in the Source field or click the first icon to
chroniqueur de on a tout, select the JSP file to use. This JSP is

This window enables you to add input JSP parameters. Add a parameter by clicking the + sign. Add a name in the Name column. Click the icon to the right of the row to display the
essay academic, Expression Builder window to dynamically enter a value for the XPath column. For this example, the custom JSP is using a parameter named PRIORITY to receive the task ID from the request.
King Relationships Essay! Therefore, PRIORITY is specified as the
topics, name and /tns:task/tns:systemAttributes/tns:PRIORITY is specified as the XPath expression.
Lear Essay! Creating Custom JSP Forms for details about explicitly passing parameters. This option provides the default Header1.jsp and Footer1.jsp files to display the header and footer regions, respectively. This option enables you to
high school causes essay, specify an
king lear essay XSL to convert the task XML document into an HTML document for the form. Note that this is useful only to create read-only forms. Enter the
an essay on women, HTTP location in the Source field or click the first icon to select the input XSL file to use.
15.8.5 Deploying Task Display Forms. Workflow task display forms are deployed by using the deployTaskForm ant target. This target is executed when you deploy the BPEL process from Oracle JDeveloper or from the command prompt. This target generates an EAR file that includes all generated default or custom JSPs.
Relationships Essay! This generated EAR file is deployed as a child of the Oracle BPEL Process Manager application. The following directory structure is generated. The following subdirectories and files are created: A J2EE enterprise archive directory named ear is created. EAR deployment descriptors are generated and stored in the META-INF subdirectory.
A Web archive (WAR) directory named war is
essay, created. This directory contains the following files and subdirectories: Style sheets and Java server page files for the header ( Header1.jsp ), footer ( Footer1.jsp ), and body ( payload-body.jsp and payload-body.xml ) are generated and stored in the war directory. Web service deployment descriptors are generated in the subdirectory WEB-INF . You can delete all form-related files by
king lear parent-child relationships essay, right-clicking the human task folder in the Application Navigator and
thesis on binge, selecting Delete Task Form files .
King Essay! As described earlier, you can register a custom JSP for rendering the task details in the worklist. The BPEL worklist invokes any custom JSP that has been registered.
High Dropouts! Follow these instructions to create a custom JSP form.
Get the task ID, version, and
king parent-child, context ID from the request. Get the workflow context object based on the context ID. Get the
essay academic writing, task object based on the task ID and version. Use the task query service API getTaskDetailsById if the version is
lear parent-child relationships essay, null or empty. Otherwise, use the getTaskVersionDetails API. Use the task object methods to
birth control, get the values you want to display in the JSP. In the case of
lear update support, generate the hidden HTML type for the following parameters, so that the update servlet can read these parameter values: You can get the
high dropouts causes and effects essay, values for these parameters in the custom JSP servlet request object.
Run time invokes the custom JSP by passing these parameters. The following custom JSP code shows how to use these steps to write a custom JSP that uses the local query service and verification APIs. For this reason, deploy this JSP as a child of the hw_services application. If you do not want to deploy to the same application server, replace local APIs with remote APIs. 15.8.6.1 Adding Update Support in the Custom JSP. To add update support in the custom JSP, you can write the servlet that uses the remote task service APIs to
king lear parent-child relationships, update the custom JSP task values: Get the task object by
chroniqueur de on, using the same steps as used in the custom JSP. Query the task object and set the values based on the custom JSP form. For example, if the custom JSP form allows a user to update the priority attribute, then get the priority JSP form value and call task.setPriority( newvalue ); . Use the
essay, remote task service API to
thesis for the degree of master, update the task.
Lear! Get the value from servlet parameter WORKLIST_NEXT_PAGE_PARAMETER_NAME , which the custom JSP page includes as a hidden parameter.
Redirect the page to

king essay Worklist Application. Changes made in Oracle BPEL Control to
on binge, a BPEL process that includes a human task impact how tasks display in Oracle BPEL Worklist Application: If you abort an active BPEL process instance on the Instances tab, associated tasks are marked as Stale in the Status column of the Oracle BPEL Worklist Application home page.
King Lear Relationships Essay! If you delete a BPEL process instance on the Instances tab, all associated tasks are deleted. If you undeploy a BPEL process on the BPEL Process tab, associated tasks are marked as Stale in
school and effects essay the Status column of the Oracle BPEL Worklist Application home page. 15.10 Notifications from Workflow Services. Notifications are sent to alert users of
parent-child changes to the state of a task. Notifications can be sent through any of the following channels: e-mail, telephone voice message, fax, pager, or SMS.
This section contains the following topics: 15.10.1 Configuring the Notification Channel.
Leapor Summary! After configuring the
lear parent-child relationships essay, notification service for
thesis statement, e-mail and other channels in Oracle JDeveloper, set the NotificationMode parameter for the notification service to either ALL or EMAIL in the SOA_Oracle_Home bpelsystemservicesconfigns_emails.xml file. By default, this value is set to NONE , meaning that no notifications are sent. The possible values for the NotificationMode attribute are: ALL #x2013; the e-mail, SMS, voice, fax, and pager channels are configured and notification is sent through any channel.
EMAIL #x2013; Only the e-mail channel is configured for
king lear parent-child essay, sending notification messages. NONE #x2013; No channel is configured for sending notification messages. This is the default setting. The notifications for a task can be configured during the creation of
mary leapor on women summary a task in the Human Task editor. Notifications can be sent to different types of participants for different actions.
King Essay! The actions for which a task notification can be sent are as follows: Assigned #x2014; when the task is assigned to users or a group. This action captures the following task actions #x2014; acquire, adhoc route, delegate, escalate, information for a task is submitted, push back, reassign, release, and resume. Task is completed.
Chroniqueur A Tout! Task is errored.
Task is expired. Information is requested for a task. Task outcome is updated. Task is suspended. Task is withdrawn. Notifications can be sent to users involved in the task in various capacities. This includes: Assignees #x2013; the users or groups to whom the task is
king parent-child relationships, currently assigned. Initiator - the user who created the task.
Creator #x2013; the user who created the task. Approvers #x2013; the users who have approved the task so far. This applies to
thesis for the of master of science, a sequential list of approvers participant type where multiple users have approved the task and a notification must be sent to all. Owner #x2013; the owner of the task. When the task is assigned to a group, each user in the group is
lear parent-child, sent a notification if no notification endpoint is
statement drinking, available for the group.
Lear Essay! Service Configuration chapter of the
academic writing topics, Oracle BPEL Process Manager Administrator's Guide for details about editing the ns_emails.xml file and (for the JAZN XML provider) users-properties.xml file.
King Lear Parent-child Essay! Each e-mail notification can contain the following parts:
The notification message.
Dropouts Essay! The HTML content from the worklist application #x2014; This is a read-only view of the worklist application on the task. Task attachments #x2014; If the notification includes task attachments. Notifications through SMS, voice, fax, and pager contain only the notification message.
Lear Parent-child! The notification message is an XPath expression that can contain static text and dynamic values.
Birth Control! In creating the
lear relationships essay, messages, only the task BPEL variable is available for dynamic values. This restriction is because the
mary summary, messages are evaluated outside the context of the BPEL process. The payload in
lear parent-child relationships the task variable is also strongly typed to contain the type of the payload for XPath tree browsing. The XPath extension function hwf:getNotificationProperty(propertyName) is
de on a tout, available to get properties for a particular notification.
The function evaluates to corresponding values for each notification. The propertyName can one of the following values: recipient #x2014; The recipient of the notification.
Lear Relationships Essay! recipientDisplay #x2014; The display name of the recipient. taskAssignees #x2014; The task assignees. taskAssigneesDisplay #x2014; The display names of the task assignees. locale #x2014; The locale of the
essay topics, recipient.
taskId #x2014; The ID of the task for which the notification is
king lear essay, meant. taskNumber #x2014; The number of the task for which the notification is meant. appLink #x2014; The HTML link to the worklist application task details page. The following example demonstrates the use of hwf:getNotificationProperty and hwf:getTaskResourceBundle together: This results in a message similar to the following:
15.10.3 Configuring Messages in Different Languages. It is possible to get internationalized messages in
birth control the notification content using one of the following methods. If you want to
lear relationships essay, use values from the resource bundle specified during the
chroniqueur de on essayer, task definition, use the XPath extension function hwf:getTaskResourceBundleString(taskId, key, locale?) . This function returns the internationalized string from the resource bundle specified in the task definition. The locale of the notification recipient can be retrieved with the function hwf:getNotificationProperty('locale') . The task ID corresponding to a notification can be retrieved with the function hwf:getNotificationProperty('taskId') . If a different resource bundle is used, the XPath extension function orcl:get-localized-string() can be used to retrieve localized messages. Task actions can be performed through e-mail if the task is set up to enable actionable e-mail (the same actions can also be performed from the Oracle BPEL Worklist Application).
An actionable e-mail account is the
king parent-child relationships essay, account in
school dropouts and effects which task action-related e-mails are received and
relationships essay, processed. This e-mail account name is
statement drinking, identified by the element actionableEmailAccountName in the configuration file SOA_Oracle_Home bpelsystemservicesconfigwf_config.xml . Ensure that you select Make e-mail messages actionable in the Notification Settings section of the Human Task editor to make e-mail notifications actionable. (See Figure 15-25.) This enables you to perform task actions through e-mail. If a notification is
lear, actionable, the e-mail contains links for each of the
high causes and effects essay, custom outcomes. Clicking on the links invokes the compose window of the e-mail client. You do not have to
king, change anything in
birth control the subject or the
king relationships, body in this e-mail.
Thesis For The Degree Of Science! If you change the content with the
king lear, NID substrings, the e-mail is not processed.
Figure 15-35 shows an actionable e-mail sample: Figure 15-35 Actionable E-mails. 15.10.5 Sending Inbound and Outbound Attachments.
Statement On Binge Drinking! If the include attachments flag is
king, checked; only e-mail is
high school and effects, sent. The e-mails include all the task attachments as e-mail attachments. Select Send task attachments with e-mail notifications in the Notification Settings section of the Human Task editor. (See Figure 15-25.)
In the actionable e-mail reply, the user can add attachments in the e-mail and these attachments are added as task attachments. In the
king lear parent-child, actionable e-mail reply, the user can add comments in the e-mail between Comments[[' and ']] and those contents are added as task comments. For example, Comments[[looks good]]. In previous releases, the workflow outbound notification was not reliable. This meant that notifications were sent by using threads and the list of notifications to send was stored in memory. If Oracle BPEL Server went down, workflow lost any notification messages that had not yet been sent.
With release 10.1.3, the workflow outbound notification service uses queues with the persistency service to send notifications to users.
High Dropouts Causes Essay! Whenever a workflow needs to send a notification to a user, it stores the task information such as notification ID, task ID, version, and so on
relationships in the dehydration store and enqueues the notification ID to
academic writing topics, the queue. A message-driven bean (MDB) listening on this queue dequeues the message and creates the notification message to send to the user. It then uses the notification service to send this message, which uses the queue with the dehydration store. 15.10.8 Sending Secure Notifications. If a notification is marked as secure in the Notification Settings section of the Human Task editor, a default notification message is used.
King Relationships Essay! (See Figure 15-25.) The default notification message includes a link to the task in the Oracle BPEL Worklist Application. You must log in to see task details. 15.10.9 Channels Used for
chroniqueur de on a tout essayer, Notifications. The channel through which a user is notified is determined by the notification preference attribute of the user specified in JAZN.
Lear Relationships! The notification preference is identified by the attribute orclWorkflowNotificationPreference . In a JAZN file-based system, the
mary, value for
lear parent-child essay, this attribute can be changed in
thesis the users-properties.xml file located at SOA_Oracle_Home bpelsystemservicesconfig . In an Oracle Internet Directory-based system, the user properties can be changed using the Oracle Delegated Administration Service.
King Lear Relationships Essay! If this attribute is not set, the e-mail channel is
mary an essay on women, used as the default.
Tasks can be configured to send reminders, which can be based on the time the task was assigned to a user or the expiration time of a task.
Essay! The number of reminders and the interval between the reminders can also be configured. The message used for reminders is the message that is
school dropouts causes essay, meant for ASSIGNEES when the
parent-child relationships, task is marked as ASSIGNED .
Thesis Degree Of Master Of Science! You set reminders in the Notification Settings section of the Human Task editor. (See Figure 15-25.) Reminder configuration involves these parameters. Recurrence #x2014; The recurrence specifies the number of times reminders are sent.
King Parent-child Essay! The possible values for
mary on women, recurrence are EVERY , NEVER , 0 , 1 , 2 #x2026;, 10 . RelativeDate #x2014; The relativeDate specifies if the reminder duration is computed relative to the assigned date or to the expiration date of the task. The possible values for the relativeDate are ASSIGNED and EXPIRATION .
King Relationships! Duration #x2014; The duration from the
essayer, relativeDate and the first reminder and each reminder since then. The data type of duration is xsd:duration , whose format is defined by

Lear Relationships! 15.12.2 Security Model for Services.
With the exception of the
birth control, identity service, all services that use the above-mentioned APIs (SOAP, remote EJB, local EJB, and
king parent-child essay, Java WSIF) require authentication to be invoked.
Drinking! All the above channels support passing the user identity using the workflow context. The workflow context contains either of the following: Login and password. The task query service exposes the authenticate operation that takes the login and password and returns the workflow context used for all services. Optionally, with each request, you can pass the workflow context with the
lear relationships, login and password. The authenticate operation also supports the concept of creating the context on behalf of a user with the admin ID and admin password. This enables you to create the context for a logged-in user to the Oracle BPEL Worklist Application if the password for
writing topics, that user is not available. 15.12.2.1 Security in SOAP Web Services.
SOAP Web services also support Web service security.
King! When Web service security is used, the workflow context does not need to be present in the SOAP input. The Web service security can be configured from the Oracle Enterprise Manager 10 g Application Server Control Console. Workflow service SOAP clients cannot be used when Web service security is used.

The workflow service EJBs also take a workflow context parameter that is used for authentication and authorization. 15.12.2.3 Creating Workflow Context on Behalf of a User. The authenticate API operation on the task query service can create the workflow context on behalf of a user by passing the user ID and password of an admin user in the request. An admin user is a user who has the BPMWorkflowAdmin role. This created context is as if it was created using the password on behalf of the user.
In this example, the workflow context is created for user jcooper . The task service exposes operations to act on tasks. Table 15-17 describes the operations of the task service.
King Lear Parent-child! Package oracle.bpel.services.workflow.task corresponds to the task service. Table 15-17 Task Service Methods.
Birth Control! The task query service queries tasks based on a variety of

This only returns tasks where the string is contained in the task title, task identification key, or one of the task text flex fields. predicate #x2014; An optional oracle.bpel.services.workflow.repos.Predicate object that allows clients to specify complex, SQL-like query predicates. Note: To use the task query service over SOAP, call Predicate.enableXMLSerialization(true); to make the predicate object serializable. This section describes the identity service component of
king Oracle BPEL Process Manager. The identity service is a thin Web service layer on top of the Oracle Application Server 10 g security infrastructure, namely OracleAS JAAS Provider (JAZN), or any custom user repository. It enables authentication and authorization of users and the lookup of user properties, roles, group memberships, and privileges. Some users and roles are automatically created when Oracle BPEL Process Manager is
chroniqueur essayer, installed. Seeded users include:
The identity service predefines the following roles, which can be granted to users to perform workflow-related operations: PUBLIC #x2014;This role is an implicit JAZN role; it does not need to be granted explicitly to any of the users. If any user can authenticate with the worklist, then they can see tasks assigned to them or groups they belong to and act on these tasks. The BPMPublic role can be used and
king parent-child, explicitly granted to each user if a third-party provider does not support an implicit PUBLIC role. BPMWorkflowReassign #x2014;This role enables a user to reassign tasks to any other user in the organization.
A manager can always delegate tasks to any users under him in the organization hierarchy without any Reassign privileges. However, to reassign to users outside the management hierarchy, the
thesis statement drinking, BPMWorkflowReassign role is required.
Parent-child! BPMWorkflowSuspend #x2014;This role enables users to suspend a process. If a process is
birth control, suspended, then the expiration time does not apply. When the process is resumed, the expiration date is recomputed. Users cannot suspend the workflow if the process designer has designated Suspend as a restricted action, even if the user has the BPMWorkflowSuspend role. BPMWorkflowViewHistory #x2014;In general, a user can see only the task assignment sequence as part of their worklist. This role enables a user to
lear relationships, drill down further into the BPEL business process audit trail from the task approval sequence.
BPMWorkflowAdmin #x2014;This role enables a user to perform system actions on
birth control any workflow in the system. This role does not allow you to change the outcome of the task (such as approve or reject); it only allows you to perform actions such as delegate, escalate, and suspend. Only the task assignee or the task owner can change the outcome of the task. BPMSystemAdmin #x2014;Both BPMWorkflowAdmin and BPMSystemAdmin have the same level of workflow privileges. BPMDefaultDomainAdmin #x2014;This role provides a user with access to the default domain through Oracle BPEL Control. Oracle BPEL Process Manager Administrator's Guide for instructions on configuring the identity service and
king lear relationships essay, additional details about the BPMSystemAdmin and BPMDefaultDomainAdmin roles. Some of these roles are nested. The BPMWorkflowReassign , BPMWorkflowSuspend , and BPMWorkflowViewHistory roles are granted to
birth control, the BPMWorkflowAdmin role. The BPMSystemAdmin role is granted to the seeded bpeladmin user. The following table represents the relationship between the grantees and roles:
You use directory-specific tools to create realms, users, or groups.
King Lear Parent-child Essay! For example: To create users and
thesis of science, groups when using OID, you use the Oracle Delegated Administration Services tools. See Oracle Identity Management Guide to Delegated Administration for more information. To create user and group credentials when using the XML-based JAZN provider, you use the JAZN Admintool to modify the jazn-data.xml file.
Relationships Essay! To add or remove an
chroniqueur a tout essayer XML-based JAZN user or role, the JAZN Admintool must be used.
You can manually edit the users-properties.xml file to specify detailed user properties that JAZN does not support. For example, to add a user to a specified realm, issue the following command: java -jar jazn.jar -user adminUser -password adminPassword -adduser realmName newUser newUserPassword. The JAZN Admintool provides different command options. You can list all the options and their syntax with the -help option, as in: java -jar jazn.jar -help.
If you are using a third-party LDAP server or a custom user repository, you must use the specific tools available for that directory. 15.12.5.2 Identity Service Providers. Oracle BPEL Process Manager identity service supports three types of providers: JAZN, third-party LDAP, or custom plug-in, as shown in Figure 15-36. Figure 15-36 Identity Service Providers. The identity service providers perform the following operations: Authentication#x2014;authenticates users given their username and
king lear parent-child, password. Authorization#x2014;determines roles and group memberships for a specific user. These roles are then used to control access to various work items and operations on the worklist.
Mary Leapor On Women Summary! Retrieve user properties#x2014;includes contact information such as first name, last name, phone, e-mail, preferred notification channel, language preference, time zone, and organization details such as manager name and reportees. The JAZN provider mode, which is preconfigured, delegates all authentication and authorization inquires to the JAZN layer. Two JAAS providers are supplied as part of the OC4J security infrastructure: the XML-based file and LDAP-based OID.
XML-Based JAZN Provider Type #x2014; The XML-based provider type is
lear relationships, used for lightweight storage of
essay academic topics information in the XML files. All the
king lear essay, user names, roles, and permissions are stored in XML files. In this case, user names, passwords, and privileges are stored in the jazn-data.xml file. In addition, Oracle BPEL Process Manager uses a user-properties.xml file that works in conjunction with this file to store detailed user properties such as name, e-mail, phone, and manager.
Dropouts Causes And Effects Essay! LDAP-Based JAZN Provider Type (Oracle Internet Directory) #x2014; The LDAP-based provider type is
king, based on the Lightweight Directory Access Protocol (LDAP) for centralized storage of information in a directory.
OID is a standard LDAP-based directory that provides a single, centralized repository for all user data. It allows sites to manage user identities, roles, authorization, and authentication credentials, as well as application-specific preferences and
high school dropouts causes and effects, profiles in
king essay a single repository.
For The Of Master Of Science! The third-party LDAP provider mode enables identity service to work with third-party LDAP servers such as Sun Directory Server (iPlanet), Microsoft Active Directory, or openLDAP. In this mode, identity service assumes that the directory is the central repository of all user data, including authentication credentials, roles, and profiles. The standard organizationalPerson , inetOrgPerson objects from the LDAP schema retrieve these details.
15.12.5.2.3 Custom User Repository Plug-ins. This mode enables you to plug in a non-LDAP-based user repository by registering a custom identity service provider. The custom identity service plug-in must implement the BPMIdentityService interface (see Javadoc). This identityservice class name must be registered in is_config.xml . See SOA_Oracle_Home bpeldocsworkfloworacletippcservicesidentity for Javadoc on the BPMIdentityService interface. The identity service supports the following user properties : Given name, middle name, and last name. Home phone number.
King Relationships! Mobile phone number. Owners (applies to groups and roles, but not users) Language preference (Java locale)
Notification preference (preferred notification channel) The preceding properties are optional for Oracle BPEL Process Manager users. However, some features, such as task notification, are not available if the
mary an essay on women, contact information is
essay, not present in
essay academic writing the directory or in the users-properties file for the JAZN XML-based provider. Also, automatic escalation and manager views are not available if the manager field is not available to
lear parent-child relationships essay, the identity service. If the user is
birth control, not listed among the owners of the group, they cannot modify the
king lear parent-child essay, rule defined for the group. The service configuration chapter of Oracle BPEL Process Manager Administrator's Guide for
high school causes and effects, instructions on defining group ownership.
Parent-child Relationships! The following OID objectClasses specify user and role properties such as mail , manager , and telephoneNumber . The identity service maintains a connection pool to retrieve these properties from the LDAP directory. If you are using the XML-based JAZN provider, the same entries are represented as XML elements in the users-properties.xml file in. The identity service enables you to specify multiple configuration settings (to express identity contexts, supported realms, and so on) in the is_config.xml file.
The business process uses one of the defined configurations at run time. The configuration must specify the realm name to enable a business process to resolve the context at run time. For the
birth control, JAZN provider, the realm name must match one of
lear supported JAZN realm names. Otherwise, a run time exception is thrown.
A Tout Essayer! For the
lear parent-child, JAZN XML-based provider, extended user and
for the of master, role properties for different realms must be stored in different files.
For the LDAP provider, the realm name can be any unique name, while the context is defined by
relationships, the LDAP URL, user search base, and role search base nodes in the LDAP server tree. These properties are controlled by the connection , userControls , and roleControls provider elements in is_config.xml . If the is_config.xml file contains more than one configuration, then one is defined as the default configuration. The default context is used by the BPEL process if no specific context information is found at run time. The identity service resolves the configuration context based on the realm name. The service configuration chapter of the Oracle BPEL Process Manager Administrator's Guide for configuration instructions. 15.12.5.5 Authentication, Authorization, and Identity Service Providers.
High Dropouts! The identity service supports authentication, authorization, and
king lear relationships, identity service providers. The identity service provider is the default pseudoservice provider. It must be defined for each configuration in the is_config.xml file. It delegates all calls either to
thesis for the of master of science, the authentication or authorization service provider.
By default, all three service providers share the same context setting defined in
king lear parent-child relationships essay the identity provider.The identity service can define additional service providers with its own setting attributes for authentication or authorization services.If the provider service attribute is set to Authentication , the setting and the provider context are used only for all authentication calls for the configuration.
Essay Writing! If the provider service attribute is set to Authorization , the
king relationships essay, setting and
leapor, provider context are used only for authorization calls. The multiple service providers section of the
lear parent-child relationships essay, service configuration chapter of the Oracle BPEL Process Manager Administrator's Guide for an example of a configuration with two providers: The JAZN XML-based identity service provider is used for all calls, except authentication. The custom plug-in provider is used only for authentication calls.
The notification service exposes operations that can be invoked from the
essay academic, BPEL business process to send notifications through e-mail, voice, fax, pager, or short message service (SMS) channels. Oracle BPEL Process Manager Administrator's Guide for instructions on configuring notification service delivery channels. Task metadata service exposes operations to retrieve metadata information related to a task. Table 15-19 describes these methods. Package oracle.bpel.services.workflow.metadata corresponds to the task metadata service.
Table 15-19 Task Metadata Service Methods. The user metadata service provides methods for managing metadata specific to individual users and groups. It is
king lear essay, used for getting and setting user worklist preferences, managing user custom views, and managing workflow rules for users and
of science, groups. For most methods in the user metadata service, the authenticated user can query and
king lear parent-child relationships essay, update their own user metadata. However, they cannot update metadata belonging to other users.
On Women Summary! In the case of group metadata (for example, workflow rules for groups), only a user designated as an owner of a group (or a BPMWorkflowAdmin user) can query and update the metadata for that group. However, a user that has been granted the BPMWorkflowAdmin role can query and update metadata for any user or group. Table 15-20 describes the methods in the user metadata service. Package oracle.bpel.services.workflow.user corresponds to the user metadata service.
Table 15-20 User Metadata Service Methods.
King Lear Parent-child! Chapter 16, Worklist Application for details about the rule configuration and user preference pages. The runtime config service provides methods for managing metadata used in the task service run time environment. It principally supports management of task payload flex field mappings. The task object used by the task service contains a number of flex field attributes, which can be populated with information from the
de on essayer, task payload.
King Lear Relationships! This allows the
birth control, task payload information to be queried, displayed in task listings, and used in workflow rules.
The runtime config service allows administrators to create mappings between simple task payload attributes and these flex field attributes. Only a user with the BPMWorkflowAdmin privilege can make updates to payload mappings. However, any authenticated user can use the query methods in
king lear essay this service.
On Binge Drinking! An administrator can create attribute labels for the various flex field attributes.
Parent-child Relationships Essay! These attribute labels provide a meaningful label for the attribute (for example, a label Location may be created for the flex field attribute TextAttribute1 ). A given flex field attribute may have multiple labels associated with it.
Essay Academic Writing! This attribute label is
lear parent-child relationships essay, what is displayed to users when displaying lists of attributes for a specific task in the worklist application. The attribute labels for a specific task type can be determined by calling the getTaskAttributesForTaskDefinition method on the task metadata service. When defining attribute labels, the following fields are automatically populated by
essayer, the service. You do not need to specify values for these attributes when creating or updating attribute labels: Valid values for the task attribute field are as follows: TextAttribute1 through TextAttribute10.
FormAttribute1 through FormAttribute5. UrlAttribute1 through UrlAttribute5.
King Parent-child Essay! DateAttribute1 through DateAttribute5. NumberAttribute1 through NumberAttribute5.
For The! Mappings can then be created between task payload fields and the attribute labels. For example, the
king essay, payload field customerLocation can be mapped to the attribute label Location . Different task types can share the same attribute label. This allows payload attributes from different task types that have the same semantic meaning to
chroniqueur a tout, be mapped to
king parent-child relationships, the same attribute label. Only payload fields that are simple XML types can be mapped.
The runtime config service also provides methods for querying the dynamic assignment functions supported by
thesis statement on binge drinking, the server. Table 15-21 describes the methods in the runtime config service. Package oracle.bpel.services.workflow.runtimeconfig corresponds to
king lear relationships, the runtime config service. Table 15-21 Runtime Config Service. 15.12.9.1 Internationalization of Attribute Labels. Attribute labels provide a method of attaching a meaningful label to a task flex field attribute. It can be desirable to present attribute labels that are translated into the appropriate language for the locale of the user.
Mary On Women! To achieve this, you can add entries to the WorkflowLabels.properties resource property file, and associated resource bundles in other languages. This file exists in the SOA_Oracle_Home bpelsystemservicesconfigwfresource directory. Entries for flex field attribute labels must be of the form:
For instance, the entry for a label named Location is: Note that adding entries to these files for attribute labels is optional. If no entry is present in the file, the name of the attribute label as specified using the
king parent-child relationships, API is used instead. 15.13 Configuring the Assignment Service.
Birth Control! This section describes how to configure the assignment service. This section contains the following topics: 15.13.1 Dynamic Assignment Functions.
Dynamic assignment functions select a particular user or group from either a group, or from a list of users or groups.
King! The selection is made according to criteria specific to the particular dynamic assignment function. The three dynamic assignment functions shown in
thesis statement on binge drinking Table 15-22 are included with Oracle BPEL Process Manager: Table 15-22 Dynamic Assignment Functions. These functions all check a user's vacation status.
A user that is currently unavailable is
lear parent-child, not automatically assigned tasks. These dynamic assignment functions can be called using the custom XPath functions in a BPEL process or task definition. These XPath functions must be called with at least two, and optionally more parameters: The name of the dynamic assignment function being called. The name of the group on which to execute the function (or a list of users or groups).(Optional) the identity realm to
statement on binge drinking, which the
parent-child essay, user or group belongs (default value is the
chroniqueur essayer, default identity realm). Additional optional parameters specific to the dynamic assignment function. In the
king lear relationships, case of the most-productive assignment function, this is the length of time (in days) to calculate a user's productivity.
The two other functions do not use additional parameters. In addition, workflow rules created for a group can use dynamic assignment functions to select a member of that group for reassignment of a task.
Statement Drinking! In addition to the three functions, a dynamic assignment framework is
lear relationships, provided that allows you to implement and configure your own dynamic assignment functions. 15.13.1.1 Implementing a Dynamic Assignment Function. To implement your own dynamic assignment function, write a Java class that implements one or both of the
essay topics, following interfaces: If your dynamic assignment function selects users, implement the first interface. If it selects groups, implement the
lear essay, second interface. If it allows the selection of both users and groups, implement both interfaces.
Dropouts! The two interfaces above both extend the
king lear parent-child relationships essay, interface oracle.bpel.services.workflow.assignment.dynamic.IDynamicAssignmentFunction . Your Java class should also implement the methods in that interface. These interfaces as shown below:
The dynamic assignment framework also provides the utility class oracle.bpel.services.workflow.assignment.dynamic.DynamicAssignmentUtils . This class provides a number of methods that are useful when implementing dynamic assignment functions. 15.13.1.2 Configuring Dynamic Assignment Functions. Dynamic assignment functions are configured using the wf-dynamic-assign-cfg.xml file in the SOA_Oracle_Home bpelsystemservicesconfig directory. Each dynamic assignment function must have an
chroniqueur de on entry in this file, in the form of a function tag. The function tag must contain two attributes: name #x2014; the name of the
essay, function. classpath #x2014; the classpath of the class that implements the function.
Academic! In addition, the
parent-child relationships, function tag can optionally contain any number of property tags. These tags pass initialization parameters to the dynamic assignment function.
Birth Control! Each property tag must contain a name attribute.
The value of the property is specified in the body of the tag. The property values specified in these tags are passed as a map (indexed by the value of the
king lear relationships essay, name attributes) to the setInitParameters method of the dynamic assignment functions. Two of the functions have initialization parameters. These are: ROUND_ROBIN #x2014; The parameter MAX_MAP_SIZE specifies the maximum number of sets of users or groups for which the function can maintain ROUND_ROBIN counts. The dynamic assignment function holds a list of users and groups in memory for each group (or list of users and groups) on which it is asked to execute the ROUND_ROBIN function.
For The Of Master! most-productive #x2014; The parameter DEAFULT_TIME_PERIOD specified the length of time (in days) over which to
lear parent-child relationships, calculate the user's productivity. This value can be overridden when calling the most-productive dynamic assignment function. Use an XPath function by
causes and effects, specifying an alternative value as the
lear relationships, third parameter in the XPath function call. 15.13.1.3 Configuring Display Names for
chroniqueur a tout essayer, Dynamic Assignment Functions.
The runtime config service provides methods for returning a list of available user and group dynamic assignment functions.
Parent-child Essay! These functions return both the name of the function, and a user-displayable label for the function. The functions support localization of the display name, so that it displays in the appropriate language for the context user. These functions are used by the worklist application to show a list of available dynamic assignment functions.
A Tout Essayer! To specify display names (and appropriate translations) for your dynamic assignment functions, add entries to the resource property file WorkflowLabels.properties , and associated resource property files in
essay other languages.
Chroniqueur A Tout Essayer! This file exists in the SOA_Oracle_Home bpelsystemservicesconfigwfresource directory. Entries for
king essay, dynamic assignment functions must be of the
birth control, form: For instance, the entry for the ROUND_ROBIN function is: Note that adding entries to these files for dynamic assignment functions is optional. If no entry is present in the file, then the name of the function (for example, ROUND_ROBIN ') is used instead. 15.13.2 Dynamically Assigning Task Participants with the Assignment Service.
Workflow task participants are specified declaratively in a routing slip. The routing slip guides the workflow by specifying the participants and how they participate in the workflow task (for example, management chain hierarchy, sequential list of approvers, and so on). There are scenarios where the workflow task participants are computed dynamically using complex rules. To support such dynamic assignment, an
relationships assignment service is used. The assignment service is responsible for determining the task assignees.
De On A Tout Essayer! You can also implement your own assignment service and plug in that implementation for use with a particular workflow. This section contains the following topics: 15.13.2.1 Assignment Service Overview.
